Maxwell’s curl equations lead to energy transport via electric and magnetic fields because spatial variations of one field lead to a temporal change in the other. The finite-difference time-domain (FDTD) method of calculating electromagnetic fields takes advantage of this interplay of the fields by using a suitable gr…
We consider the quantization of the effective target space description of topological M-theory in terms of the Hitchin functional whose critical points describe seven-manifolds with G2 structure. The one-loop partition function for this theory is calculated and an extended version of it, that is related to generalized…
Crimped mineral wools are characterized by a strongly anisotropic microstructure, whose local preferential orientation is highly heterogeneous. It is proposed to identify the local anisotropic elastic behavior through a combination of different tools based on image analysis. First, the local orientation map is determi…
The very potent greenhouse gas nitrous oxide (N 2 O) is widely used as a mild anaesthetic for mothers in delivery work in Sweden. As a part of the Stockholm County Council environmental program it was decided in 2002 that the emissions should be drastically reduced. Different ways were theoretically evaluated, and cat…
In this report, we provide an x-ray magnetic circular dichroism (XMCD) study for 100nm thick epitaxial magnetite (Fe3O4) films on MgO (001) and Al2O3 (0001) substrates. For XMCD, we recorded the surface sensitive total electron yield and the bulk sensitive transmission spectra. From the analysis of the XMCD data, we f…
Abstract A new series of (diisopropylcarbamato)(oxido)zinc complexes were obtained by innovative synthetic approaches. The (carbamato)zinc clusters [Zn 4 (μ 4 ‐O)(O 2 CN i Pr 2 ) 6 ] ( 1 ) and [Zn 8 (μ 4 ‐O) 2 (O 2 CN i Pr 2 ) 12 ] ( 2 ) were synthesised by an identical reaction procedure involving protolysis of ZnEt…
The phase diagram of the Al 2 O 3 –ZrO 2 –Er 2 O 3 system was constructed in the temperature range 1200–2800 °C. The phase transformations in the system are completed in eutectic reactions . No ternary compounds or regions of substantial solid solution were found in the components or binaries in this system. Four tern…
We systematically evaluate the slow conformational reorientations of polypropylene (PP) and polyethylene- co -1-butene (PEB) chains at temperatures near T g before and after formation of a miscible blend with chain specific experiments. Solid-state 13 C CODEX and static 129 Xe NMR experiments reveal that aPP and PEB66…
A combinatorial approach was used to systematically investigate the effect of trace Pr(3+), Tb(3+), or Sm(3+) on the VUV photoluminescence of Eu(3+) in the Pr(3+), Tb(3+), or Sm(3+) co-doped (Y(0.65)Gd(0.35))BO(3):E(3+)(0.05). We found that Pr(3+) and Tb(3+)increases the VUV photoluminescent efficiency, while Sm(3+) d…
Abstract The mechanisms of oxidation of a series of a-alkyl substituted mono and dimethoxylated benzyl alcohols catalysed by mesotetrakis(4-N-methylpyridynium)porphyrin iron (III) chloride (FeTMPyPCl) and meso-tetrakis(4-sulfonatophenyl)porphyrin iron (III) chloride (FeTSPPCl) in aqueous solution with KHSO5 as oxygen…
Sol−gel materials are often reinforced through the addition of particulate fillers to improve their mechanical properties, such as toughness or stiffness. Related studies of filled polymeric materials suggest that the effectiveness of added reinforcements may depend sensitively on the state of particulate aggregation…
Abstract The epoxidation of methyl oleate with molecular oxygen in the presence of aldehydes was investigated and optimized. Epoxide yields up to 99% were observed in organic solvents. The preponderant radical reaction was started by a single organic radical chain initiator, without using a metal catalyst. The radical…
New layered pink cobalt hydroxyisocyanates have been prepared by controlled hydrolysis of aqueous solutions of CoCl2.6H2O. Co(OH)(1.4)(NCO) 0.6.0.6H 2O ( 1) is formed when urea is used as the hydrolysis agent and mannitol as the stabilizer, while Co(OH)(1.25)(NCO)(0.75).0.2H2O ( 2) is formed when the hydrolysis agent…
Scandium-doped M-type barium hexagonal ferrites of the composition BaFe12−xScxO19 are well suited for low frequency microwave device applications such as isolators and circulators. A series of Sc-doped M-type barium hexagonal ferrite powders (x=0–1.2) were prepared by conventional ceramic processing techniques. The re…
Magnetic and thermal properties of the iron(III) spin crossover complex [Fe(3MeO-salenEt)(2)]PF(6) are very sensitive to mechanochemical perturbations. Heat capacities for unperturbed and differently perturbed samples were precisely determined by adiabatic calorimetry at temperatures in the 10-300 K range. The unpertu…
The stress corrosion cracking (SCC) of a commercial Cu–30% Zn alloy has been investigated as a function of applied stress in Mattsson solutions with pH 7.0 and 10.0 at 313 K by using a constant load method. It was found that the elongation behavior at pH 10.0 showed clearly the step wise fashion, while that at pH 7.0…
Copper retention by ferrihydrite, leaf compost, and montmorillonite was studied over 8 months in systems that emulate a natural soil where different solid phases compete for Cu through a common solution in a compartmentalized batch reactor. Copper speciation in solution (total dissolved, DPASV-labile, and free) and ex…
The thermal response of epitaxial Bi films deposited on Si(001) upon femtosecond laser pulse excitation is investigated by means of ultrafast electron diffraction. The initial surface temperature increase is caused by linear absorption of $800\phantom{\rule{0.3em}{0ex}}\mathrm{nm}$ photons. The exponential decay of th…
The epidermis of fish is covered with a layer of mucus, which contributes to the defence of the species against parasites, bacteria and fungi. We have previously extracted glycoproteins from various mucus samples from fish and have shown that they present pore-forming activities well correlated with strong antibacteri…
